A great presentation on the predictability of bubble burst.
Watching just the video itself is not enough because Mr. Sornette also talked to Ted and provided his predictions and analysis on various global markets. You can read by following the link below.
Turbulent times ahead: Q&A with economist Didier Sornette
(For the eternal bulls of the US stock market – sorry, not a bearer of good news this time.)
One thing interesting is his measures on the risk level in May 2013 somehow match closely to the timing of my call in real-time chat for a potential sudden drop in S&P with significant size. In another words, his use of power law distribution analysis on market activities may work similarly to my custom breadth analysis.
It is very encouraging to see academic research finally producing something useful with predictive value.
